Using natural disasters to instigate radical policy changes. The effect of Fukushima nuclear power plant accident on nuclear energy policies : Natural hazards 2013
Natural disasters and their effects reflect the interlinking physical and human environment of the modern world. After the earthquake and tsunami in Fukushima (2011), activists, lobbyist and reporters quickly judged nuclear technology and demanded
Small-scale effects of annual and woody vegetation on sediment displacement under field conditions
The AA. examined the effects of mound-forming shrubs and annual plants on sediment dispersal at small spatial scales in the semi-arid shrubland of the northern Negev Desert of Israel. They conducted a field experiment to test the displacement
and removal of annuals and their litter. It is showed that : most sediment displacement was caused by rainsplash; overhead cover by shrub canopy had the largest reducing effect on sediment loss; Removal of low annual herbs and litter increased sediment loss
Field studies on the effects of three geotextiles on runoff and erosion of road slope in Beijing, China
In order to examine the effects of 3 kinds of geotextiles (shade net, non-woven fabrics and straw mats) on road slopes in decreasing runoff and soil loss, a self-made rainfall simulator was calibrated and used in a field experiment on slopes of Jing
runoff and sediment concentration compared with the bare slope. Furthermore, straw mats had the best effect among them, resulting in the lowest runoff coefficient and sediment yield.
Scaling effects of landscape metrics : a comparison of two methods
This study compared 2 strategies, including a high-resolution-data-based resampling (RS) approach and a multisource and multiresolution data (MSMRD) approach, to quantify the grain effects of 9 commonly used landscape metrics determined by FRAGSTATS
software. Three adjacent, small watersheds in the central Loess Plateau of China were selected as study sites. Using the RS and MSMRD approaches, 5 and 7 landscape metrics, respectively, were detected to have significant and mostly linear grain effects

Estimating the effect of Pinus massoniana Lamb plots on soil and water conservation during rainfall events using vegetation fractional coverage
Quadratic polynomial regression models were established for 5 pure tree (Pinus massoniana Lamb) plots between vegetation fractional coverage (VFC) and soil/water conservation effects (SCE/WCE) for 144 erosive rainfall events from 2007 to 2010
in Hetian Town, Changting County, Fujian Province. In general, the effects on soil conservation on the plots were more notable than those on water conservation. The critical VFCs for soil and water conservation during rainfall events were 0.4 and 0.5
Effects of interrill erosion, soil crusting and soil aggregate breakdown on in situ CO2 effluxes
of measurements did not have a significant effect. This leads to the conclusion that crusting and interrill erosion has no or only a minor effect on in situ CO2 effluxes.
Modeled effects of climate change on actual evapotranspiration in different eco-geographical regions in the Tibetan Plateau
From 1981 to 2010, the effects of climate change on evapotranspiration of the alpine ecosystem and the regional difference of effects in the Tibetan Plateau (TP) were studied based on the Lund-Potsdam-Jena dynamic vegetation model (LPJ) and data
Large roughness element effects on sand transport, Oceano Dunes, California
The effect of large roughness elements on sand transport efficiency was evaluated on a coastal sand sheet by measuring sand flux with 2 types of sand traps [Big Spring Number Eight (BSNE) and the Cox Sand Catcher (CSC)] at 30 positions. The sediment
transport measurements were made in the Oceano Dunes State Vehicular Recreation Area, Oceano, California, in support of a study to evaluate the effectiveness of emplaced roughness to control sand movement and dust emissions. Measurements of local winds
Characterization of the effect of tillage on furrow irrigation hydraulics for the Dire Dawa Area, Ethiopia
A study was conducted to evaluate the effect of tillage method and depth on furrow irrigation hydraulics and soil water storage during the dry season at Dire Dawa, Eastern Ethiopia. Treatments in the study included were chisel, moldboard and disk
decreased tail water ratio and distribution uniformity in the first two irrigations, but had little effect during the successive irrigations.
Effects of fire on soil organic matter quality along an altitudinal sequence on Mt. Etna, Sicily
and drier climate. They evaluated the effect of fire on the chemical and physical characteristics of SOM along the altitudinal sequence. At 2 sites at a similar altitude but having a different recent fire history, they also examined the effect of fire
Effects of land use, slope gradient, and soil and water conservation structures on runoff and soil loss in semi-arid Northern Ethiopia
The aim of this study was to investigate the effects of typical land-use types, slope gradients, and different soil and water conservation (SWC) structures on runoff and soil loss at the runoff-plot scale. Six runoff measuring sites, corresponding
. It is highlighted that the effects of SWC structures on runoff production and soil loss are considerable; hence, it is crucial to consider these effects for optimal design of water-harvesting schemes such as micro-dams that collect and store surface runoff
be interpreted as the implied total impact effects defined as the sum of direct and indirect spatial feedback effects. The model is illustrated by analyzing patent citation flows data across European regions.
